Team determines first high-resolution structure of dopamine receptor
(PHYSorg.com Chemistry)

One way or another, many psychiatric drugs work by binding to receptor molecules in the brain that are sensitive to the neurotransmitter dopamine, a chemical signal that is central to how our experiences shape our behavior. But because scientists still don`t understand the differences between the many kinds of dopamine receptors present on brain cells, most of these drugs are `messy,` binding to multiple different dopamine receptor molecules and leading to serious side effects ranging from movement disorders to pathological gambling.
